Is grep 𝘳𝘦𝘢𝘭𝘭𝘺 all your AI agent needs for search?
For a small codebase or a docs folder, the answer might be yes, but in most enterprise environments, agents face millions of PDFs, spreadsheets, and scanned documents. Lexical search alone can't read those formats, doesn't scale, and misses synonyms entirely.
In our latest post, we break down:
→ Where grep shines (and why it's not going away)
→ Why RAG and semantic search are necessary at enterprise scale
→ How to layer lexical + semantic search for the best of both worlds
The answer isn't grep vs. RAG, it is knowing when to reach for each and how to combine them.
